parametric fillets or chambers
So let say you have your shape.


In Edit mode, select an edge and bevel it.





Back to Object mode, create one shapekey (Basis) then a second one.





Keep the second shapekey selected. Back to Edit mode, select the corner and scale it down with SShiftX so that it doesn't scale on the X axis.





Enable the Snap tool, Vertex mode. Move the bevel on the Z axis (GZ), use the snap to align to the right level. Then move the bevel on the Y axis (GZ), use the snap to align to the right level.





Now back to Object mode, when you select the second shapekey and play with the Value, the bevel shrinks to its new radius.
